YOKOGAWA · CENTUM ENGINEERING RECORD
Yokogawa ATSA3S-0 and Yokogawa ATSA3D-0 are pressure-clamp terminal blocks for the ASI133 eight-channel analog input module with built-in barriers. ATSA3S-0 serves one module, while ATSA3D-0 provides the dual-redundant terminal arrangement for two adjacent ASI133 modules.
Field current enters Yokogawa ATSA3S-0 or Yokogawa ATSA3D-0 at the paired A/B terminal map and is routed to the assigned ASI133 input. The map supports 2-wire and 4-wire transmitter circuits, using input, return and ground positions according to the documented channel pattern.
The terminal block does not perform signal conversion. Yokogawa ATSA3S-0 and Yokogawa ATSA3D-0 organize pressure-clamp field termination and the mechanical handoff to ASI133, so conductor identity and redundancy layout must be preserved during installation or replacement.

ATSA3S-0 and ATSA3D-0 are installed by preserving the complete conductor map and the selected single or redundant module arrangement.
Before removal, record channel, terminal number, polarity and whether the transmitter is 2-wire or 4-wire; do not rely only on cable color.
Mount ATSA3S-0 for one ASI133 or ATSA3D-0 for the dual-redundant pair, confirming mechanical seating before conductors are tightened.
Land input and ground conductors in the published A/B positions, torque the pressure clamps as specified, then perform continuity and loop checks before energizing the barrier circuits.
The terminal blocks connect hazardous-area field loops to ASI133 without changing the signal; redundancy is created by the module/terminal arrangement.
ATSA3S-0 routes each field loop to one ASI133, keeping the eight channel terminal identities visible at the pressure-clamp face.
ATSA3D-0 distributes the documented terminal arrangement to two adjacent ASI133 modules so the redundant execution shares the intended field wiring handoff.
Because the block is passive, conversion, HART behavior and barrier action remain functions of ASI133; terminal faults are investigated as wiring and contact problems.
Yokogawa ATSA3S-0 / ATSA3D-0 are the documented pressure-clamp terminal blocks for the ASI133 analog input module with built-in barrier.
Yokogawa ATSA3S-0 / ATSA3D-0 serve a single ASI133 and a dual-redundant pair of adjacent ASI133 modules respectively.
No. Yokogawa ATSA3S-0 / ATSA3D-0 are passive terminal blocks; signal conversion, isolation and barrier behavior belong to the connected ASI133 module.
For Yokogawa ATSA3S-0 / ATSA3D-0, use the published A/B terminal map for input, return and ground positions; do not infer a 4-wire layout from a 2-wire channel.
Before replacing Yokogawa ATSA3S-0 / ATSA3D-0, record every terminal number, channel, polarity, wire count and the single or dual module arrangement.
With Yokogawa ATSA3S-0 / ATSA3D-0, recheck conductor seating, terminal position, loop continuity and the ASI133 channel because the passive block does not correct a field or module fault.
